This invention relates to beverage dispensing devices of the type shown and described in my co-pending application, Serial No. 468,722, filed Dec. 11, 1942, now Patent No. 2,379,532, for Beverage dispensing devices. More particularly my invention is directed towards an improved construction for dispensing faucets.

One of the objects of my invention is to pro-y vide a novel and improved dispensing faucet which shall :be so constructed and arranged that syrup under pressure and charged water under pressure may be fed simultaneously from their respective sources of supply through the said faucet continuously and directly into a tumbler, the said faucet being additionally provided with an improved single control means for automatically permitting or stopping the simultaneous flow of water and syrup.

Another object of my invention is to provide a novel and improved dispensing faucet of thecharacter described designed for controlling the flow of syrup and charged water from their respective sources of supply directly into a tumbler to be mixed therein, in which the means for feeding the syrup and charged water are so arranged that changes in the relative proportional pressures under which the syrup and charged water ow will be reduced to a minimum whenever the pressures at the sources of sup-ply change.

Still another object of my invention isto provide a dispensing faucet of the class described which shall be characterized by the compactness and simplicity of its construction and assembly.v

Other objects of my invention will become apparent as the description proceeds or Will hereinafter be pointed out.

In the accompanying drawing, y

Fig. 5 is a cross-sectional view taken substantially along the line 5-5 of Fig. 3; and

Fig. 6 is a cross-sectional'view taken onY the line 6 6 of Fig. 3. A k f Referring now in detail to the drawing I have 6 Claims. (Cl. 225-26l shown a beverage' dispensing device constructed flared Y member terminating n f shoulder Illa adapted to abut a supporting wall W,

and comprising generally a spout portion I0, a control valve portion Il and an inlet portionfl2. The inlet portion I2 may comprise a longitudinal in an abutment and a pipe-like portion I2`b extending' through an opening I4 in the support W. The pipe portion I2b may be externally threaded and a correspondingly threaded nut I5 provided to maintain the beverage device in firm attachment to said support. The valve portion II is fiXedly attached to the inlet portion I2 by any suitable means, such as, for example, by providing a reduced shoulder I 2c at the end of the inlet I2 which is frictionally received in a correspondingly shaped recess I Ia in the valve portion I I and the two members are welded together as shown by the numeral I in Fig. 1 of the drawing.

The control valve portion- II comprises a main body portion I'I having a circular opening I8 in one surface thereof which is adapted to freely rotatably house a valve carrier 20 having an integral web 29a extending outwardly beyond the main body portion I1 and supporting an arcuate angemember 2Ilb. A handle member 22, is attached to the flange Zb to facilitate the rotational movement of the said valve carrier 2li within the opening I8. A capomember 25 threadedly mounted on the main body portion I'I so as to close the opening I8, holds the member 20 captive within the said opening I8. To insure proper axialrotational movement of the valve carrier 2S within the opening I8, I provide an enlarged headed screw 26 in the carrier 2U and a hole 21 in the cap 25 into which the said head of said screw 26 is recelved with a slight tolerance for Vthe said screw'head. Into an opening 29 in the carrier 2l! I frictionally mount a valve shutter 39, the function and operation of which will soon be described. AY leather washer member 4B is interposed between theshutter 30 andthe bottom wall f the `opening I8.

The spout portion III comprises a tubular mem.- ber open at the bottom and threadedly attached to an annular depending flange portion IIa of the valve I I, as clearly shown in the drawing. Into the inner opening of the ange Il, I frictionallymount a ring member 5I), having a rela# tively thickened bottom, wall 58a extending below the said flange II. The ring member 5o is provided with an axial through opening 5I, sur- I rounded by a hub portion 52 to form an annular chamber 53 between the valve body II and the bottom wall 50a of the ring member 5ta. The bottom wall 50a is provided with a plurality of circumferentially arranged apertures 55 communicating with the annular chamber 53 and with the hollow area lila of the spout I0. The axial opening 5l in the ring member 50 is threaded and an externally threaded pipe member 58 is received therein, the said pipe 58 extending downwardly through the hollow area Illa and projecting slightly below the mouth of the spout l0.

The valve shutter 39 is provided with two independent substantially U-shaped passageWays for the passage of liquid therethrough. One of the said passageways designed to control the passage of charged water therethrough comprises the inlet portion Sil, the outlet portion lil and the interconnecting portion 62. The other passageway designed to control the flow of syrup comprises the inlet portion lil, the outlet portion 'il and the interconnecting portion 72. The valve shutter 30 is preferably made of such thickness that the interconnecting passage portions 2 and 'l2 may be disposed at different levels.

Leading from a source of charged Water supply under pressure from any suitable well known supply source (not shown) is a feed pipe l5 (see Figs. l and 4) passing through the pipe i2?? and communicating directly with a passageway I6, in the inlet portion i2. The valve body il is provided with a passageway 'll communicating directly with the passageway 76 and leading directly to and communicating directly with the inlet port 6B of the valve shutter 3i), when the said valve shutter is in the open or registered position as shown in Fig. l of the drawing. A passageway 18 is provided in the body of the valve ll, which communicates with the annular chamber 53 and with the outlet port 6 l, when the valve is in open or eiective position as shown in Fig. l. It is thus seen, that when the shutter valve is in open position as shown in Figs. 1 to 4, charged Water will flow from its source directly to the annular chamber 53 from which it will ow downwardly through the apertures 55 and out through the mouth of the spout it and into a suitable tumbler.

As noted in my said co-pending application, Serial No. L$68,722, now Patent No. 2,379,532, syrup is contained in a suitable storage tank (not shown) under pressure and iiows directly through a feed pipe 8i] disposed in the pipe 12b, and directly through a communicating passageway 3l, in the inlet portion I2 and thence through a communicating passageway 82, leading directly to and into the inlet port iii, when the said port lli is in the open or eiective position as shown in Fig. l. A passageway 83 in the valve body, leading directly from the outlet port 'H and communicating directly with the pipe 5B.

It is thus seen, from the above description, that while the charged Water is flowing into a tumbler, directly from its source, ras above described,` the syrup will simultaneously iiow di-v rectly from its source into the tumbler. As eX- plained in my said co-pending application, Serial No. 468,722, now Patent No. 2,379,532, the relative proportions between the pressures of the charged water and syrup is Such that no matter how long the faucet is held in open position there will continue to ow a properly proportioned and sweetened beverage into the tumbler, thus eliminating the necessity of measuring chambers for the syrup.

'Ihe washer ll is provided with openings 50a, Bla and lila, corresponding to the inlet and out- 4 let ports 60, 6I and 1D, 'Il respectively, the said openings 60a, Bla, 'ma and 'Ila being aligned with the open position of the valve shutter, as shown inFigs. 1 and 4.

The Valve body li is provided with an abutment portion 99 to limit the rotational movement of the shutter 36 in a counter-clockwise direction as viewed from Fig. l, the said last named limited position being the one in which the valve 3) is in open effective position, as in Fig. 1. To close the valve 3i! to simultaneously shut on" the supply of charged water and syrup, the handle 22 is merely rotated in a clockwise position, from that shown in Fig. 1, to the position illustrated in Fig. 5. A set screw 9i, in the Valve body I l and disposed in the path of rotational movement of the iiange 20a may be provided to adjust the closed position of the Valve shutter 3U.

Threadedly mounted on the pipe 58 isla baiiie member directly in the path of the charged water which flows through the apertures 55 to prevent splashing of the charged Water directly into the tumbler. A nut may be employed to maintain the baffle 95 in any desired adjusted position.

To regulate the amount of syrup viiow so as to provide the dispensed beverage with any selected degree of flavor, I may provide a needle Valve li) of any well known standard type and dispose in the passageway 83 interconnecting the outlet ll with the pipe `53.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention and as various changes might be made in the embodiments above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.
